The Most Cold Hardy Rosemary?

Question

which is the most cold hardy Rosemary? i live in mid zone 7 but we see zone 6 weather for a week or two,every winter. where do i buy it in bulk? i want something i can use as a hedge and needs no care

Answer 1

Here are three hardy rosemary plants to zone 7, but rosemary is typically hardy to zone 9, so it is a risk to make an entire hedge out of rosemary.
